This invention relates to improvements in bobbin receivers for weft replenishing looms and it is the general object ef the invention to provide a receiver including a bag which is supported and reinforced by a frame which holds it in normal position and by which it may be inverted to empty the bobbins in it.

It is customary to provide a bobbin collector for bobbins which are discharged from the shuttle during the weft replenishing operations. In an application filed on even date herewith I have set forth a bobbin receiver having a frame which supports a bobbin receiving bag the front part of which is connected to vertical members of the frame by lacing or the like. It is an important object of my present invention to construct the bag in such a way that it will be reinforced by the frame, more particularly the vertical members thereof which extend alo-rig the front corners of the bag.

The frame has a removable pivotal connection with a support fixed `to the loomside and it is another object of the invention to construct this support in such manner that the lower part of the bag can move backwardly and forwardly between parts of the support when being placed in normal position or being removed for the purpose of emptying the bobbins.

The side members extend upwardly from the support and are then bent rearwardly to provide arms which support the top of the bag. The latter has heins which surround the vertical .members but the latter should be reinforced in order to hold the bag in proper position to receive the discharged bobbins. It is another object of my present invention to connect the upper ends of the vertical members by a brace which can be applied to the frame after the bag has been put in position on the frame.

With these and other objects in View which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth.

In the accompanying drawing, wherein two forms `of the invention are set forth,

Fig. 1 is a side elevation of a part of the loom, partly in section and showing the preferred form yof my improved bobbin receiver in normal position,

Fig. 2 is a front elevation looking in the direction of arrow 2, Fig. 1,

6 Claims. (Cl. 139--255) Fig. 4 is a side elevation looking in the directionof arrow 4, Fig. 3,v

Fig. 5 is an enlarged horizontal section on line 5 5, Fig. 1.

Fig. 6 is an enlarged front elevation looking in the direction of arrow 6, Fig. 1, and

Fig. 7 is a view similar to Fig. 6 but showing the modified form of the invention.

Referring particularly to Figs. 1 and 2, I have shown .a loom frame ID and a lay II supporting a shuttle box I2 which receives a shuttle S. `During replenishing operations of the loom the exhausted or depleted bobbins are discharged downwardly from the shuttle and are guided forwardly by a bobbin chute I3 secured to thelay under the box I2. The bobbins are ordinarily discharged when the lay is at so-called front center or in the left `hand position thereof as viewed in Fig. 1.. `During loom Voperation the chute I3 swings back and forth along a path under the shuttle box.

The receiver R for the discharged bobbins comprises essentially three parts, a stand I 5, a metal frame F, and a cloth bag B. The stand or support I 5 is secured to the loom` frame as at I6 and projects outwardly therefrom, or to the right as viewed in Fig. 2. The support is formed with a bottom cross bar II and right and left uprights `I8 and I9, respectively, as viewed in Fig.. 3. Secured to the cross bar Il is a bearing 2i) opening upwardly and provided with a forwardly and upwardly inclined lip `2l which defines an elongated recess 22 with bar I'I. `Side stops 23l shown more particularly in Fig. 3 extend forwardly from the arms I8 and I9 at the ends of the recess 22. Secured to the top of each of the uprights I8 and I9 is a leaf spring 25 which .projects forwardly and is upwardly bent as at 26.

The `frame F is preferably madeof a long piece of tubing or the like vbent to the general form shown in Figs. 1 and 2 so that it has right and left side members 3o and 3l, respectively.. These side members are joined at their bottom by an integral horizontal member or element 32 serving .the general function of a journal turnable in recess 22 and resting on bearing 23. The upper end of each of the side members is bent rearwardly and inclined Ydownwardly to form a supporting arm 33.

Each side member 3i] and 3l is provided near the lower end thereof with a iitting 35 formed with a lug or boss 36 for cooperation `with the associated spring 25. The fittings 35 `may be vsecured to .their respective Vside members in any `approved `manner as `by soldering before the l upwardly and provide the bag with an open bobbin receiving mouth M. Each of the inner and outer side walls is provided with upwardly extending straps or loops 4| through which the arms 33 extend, as shown in Fig. 1. Each vertical front corner of the bag is .provided with an elongated hem 42 through which extends the associated side member 35 or 3l. These hems extend downwardly a considerable distance along their side members and end in the vicinity of the upper ends of the uprights I8 and I9. The bottom of the bag extends rearwardly and downwardly from `the hems and is attached by proper stitching to the side and front 'and back walls of the bag.

The upper ends of the side members 39 and 3| are preferably braced byV some form of cross member which holds them in proper spaced relation and also adds rigidity to the frame F. In the preferred form of the invention each side member has sweated or otherwise secured thereto near the upper end thereof a fitting 45 located above the associated hem 42. These fitltings have hubs 45 facing each other and threaded to receive the threaded ends of a cross bar or brace 41. The right and left hubs 45 are provided with opposite hand threads and the opposite ends of the cross brace 41 have opposite hand threads cut on them to iit the corresponding threads of the hubs. The cross bars 41 are fitted to the hubs after the bag is in position on the frame and then turned to establish tight holding connection with the side members 30 and 3l for the purpose of spacing the latter and strengthening the frame. Bar 4l is preferably bent forwardly as shown in Fig. 5 to provide a hand hold spaced forwardly of the wall 40 of the bag.

In the modified form of the invention shown in Fig.V '1 fittings 50 are secured to the side members as in the preferred form, but the hubs 5I are soldered or otherwise secured to the ends of a cross brace 52 corresponding to the cross bar 41. In the modified form of the invention the cross bar 52 can be secured to the side members by an operation in which the heat is controlled ,to prevent burning of the bag.

In operation, the receiver R will ordinarily be in the position shown in Fig. 1 with the cross member 32 resting on the bearing 20 and in the recess 22. The side members 35 and 3l will extend substantially vertically upwardly and the lugs 35 will be under the springs 25 and held by them against the uprights I8 and I9 which cooperate with bearing 2B to hold frame F in normal position. The upper ends of the uprights I8 and I9 are free and define an open space 55 between them in front of the bottom of the bag. When the bag B is lled with depleted bobbins as the result of replenishing operations of the rloom the attendant will grasp the cross bar 41 and swing the frame and bag forwardly around the bearing :20 as a center until the lugs 36 are forward ofthe front ends of the springs 25. At this time all parts of the receiver will be in front of the back and forth path traversed by the chute I3, and the receiver may now be lifted from the support vI5 and inverted to empty the bobbins 4 contained therein. During this emptying operation the side members 30 and 3l support the forward part of the bag. Y

When the receiver is returned to normal position the cross bar 32 thereof is placed between the stops 23 and slippeddown into the recess 22, after which the receiver is pushedk rearwardly until the lugs 36 pass under the spring clips 25. The latter not only prevent upward movement of the receiver until after the latter has been moved forwardly of the path of the chute I3, but also assist gravity in holding the receiver in its normal position. During return movement of the bag to its normal position the lower part thereof will pass through the space 55 and assume the position shown in Fig. l. The hems 42 are sufliciently wide to be slipped over the fittings 45 and 5i! when the bag is 'attached to frame F.

From the foregoing it will be seen that I have provided a simple form of bobbin receiver including a rigid frame having side members which serve not only to sup-port the bag but also reinforce it. It will also be noted thatV the uprights I8 and I9 have their upper ends unconnected to define a space 55 through which the bottom of the bag can move when the receiver is being removed from and returned to the loom.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spiritV and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

l. In a weft replenishing loom, a support fixed with respect to the loom, a cloth bobbin receiving bag having vertically extending hems, a frame to which the bag is attached mounted on said support, and spaced Vertical side members on said frame extending through said hems to reinforce the bag. y Y i 2. In a weft replenishing loom, a support fixed with respect to the loom, a bobbin receiving bag having vertically extending hems formed on the front part thereof, and a frame to which the bag is attached removably mounted on said support, and having spaced side members extending through said hems, said side members reinforcing the bag when the frame is removed from said support and moved to a horizontal position.

3. In a bobbin receiver for a weft replenishing loom, a frame having vertically extending side members, an arm on the upper end of each side member extending rearwardly therefrom when the receiver is in working position relatively to the loom, and a flexible bobbin receiving bag suspended from said arms and having vertical hems surrounding said side members enabling the latter to reinforce the bag when the latter is turned to a horizontal position.
